摘要

Interface engineering may lead to a high performance organic photovoltaic as well as long lifetime. Incorporating the commonly used conducting polymer PEDOT:PSS with GO as an the anode interfacial layer, poly[[4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b: 4,5-b']dithiophene-2,6-diyl][3-fluoro-2-[(2-ethylhexyl) carbonyl]thieno[3,4-b] thiophenediyl]] (PTB7):fullerene derivative (PC71BM) bulk heterojunction (BHJ) organic photovoltaics (OPVs) were fabricated. This conventional OPV demonstrated a power conversion efficiency (PCE) of 7.53%, which has outperformed the highest reported PEDOT:PSS combined metal oxide, the highest reported efficiency with a solution processed PEDOT:PSS:GO interfacial layer as well as a PEDOT:PSS-based OPV (reference device). Moreover, the versatility of PEDOT:PSS:GO has also been demonstrated in the medium bandgap BHJ system employing poly[4,8-bis(5-(2-ethylhexyl) thiophen-2-yl)benzo[1,2-b;4,5-b']dithiophene-2,6-diyl-alt-(4-(2-ethylhexyl)-3-fluorothieno[3,4-b]thiophene-)-2-carboxylate-2-6-diyl] paired with PC71BM yielding an astonishing high PCE of 9.12%. We believe proper interface engineering could lead to high performance devices.
